What Paint Can You Not Paint Over
When it comes to home improvement projects, painting is often at the top of the list. A fresh coat of paint can instantly transform a space and give it a whole new look. But before you grab your paintbrush and start painting, it’s important to know what types of paint you should avoid painting over. Painting over certain types of paint can result in a less-than-desirable outcome, with issues such as poor adhesion, peeling, or uneven coverage. In this article, we’ll explore some paints that you should not paint over and the reasons behind it.

Oil-based Paints
Oil-based paints have long been used for their durability and finish. They are known for their resistance to moisture, stains, and general wear and tear. However, when it comes to painting over oil-based paints, it’s important to tread with caution. Oil-based paints create a tough, slick surface that can be difficult for other types of paint to adhere to. If you try to paint over an oil-based paint with a water-based paint, you may encounter issues with poor adhesion and peeling. It’s recommended to either remove the oil-based paint before applying a different type of paint or use a primer specifically designed to bond with oil-based surfaces.
Epoxy Paints
Epoxy paints are commonly used in high-traffic areas such as garages, basements, and industrial settings due to their durable and chemical-resistant properties. While epoxy paints are excellent for their intended applications, they are not suitable for being painted over. Epoxy paints cure to form a hard and smooth surface, making it challenging for other types of paint to adhere properly. If you attempt to paint over epoxy paint, you may experience issues such as peeling and poor adhesion. If you desire a different color or finish, it’s recommended to consult a professional and consider alternative options that are compatible with epoxy surfaces.
Glossy or high-sheen paints
Glossy or high-sheen paints are known for their smooth, shiny finish. While they can add a luxurious touch to any space, painting over these types of paints can be problematic. The glossy surface created by these paints inhibits proper adhesion, causing new paint to peel or crack over time. If you want to change the color or finish of a surface previously painted with glossy or high-sheen paint, it’s essential to properly prepare the surface before applying a new coat of paint. This may include sanding the surface to create a rougher texture for better paint adhesion or using a primer designed for glossy surfaces.
Chalkboard Paints
Chalkboard paints have gained popularity in recent years, as they allow individuals to transform any surface into a fun and functional chalkboard. While these paints are perfect for creating a playful and interactive space, they are not suitable for being painted over with conventional paints. Chalkboard paints have a unique composition that allows them to create a matte, porous surface that accepts chalk.
When you attempt to paint over chalkboard paint, the porous nature of the surface can cause the new paint to soak in unevenly, resulting in an uneven finish. If you want to change the color or texture of a chalkboard surface, it’s recommended to start by removing the existing chalkboard paint completely.
Textured Paints
Textured paints are often used to add depth and visual interest to walls and ceilings. They create a textured surface that can range from subtle patterns to more pronounced textures. While textured paints can be a great addition to any space, they present challenges when it comes to repainting. The textured surface can make it difficult for new paint to adhere properly, resulting in an uneven finish or peeling. If you have textured paint on your walls or ceilings and want to change the color or texture, it’s crucial to consider whether it’s more feasible to remove the textured paint completely or consult a professional for alternative solutions.
Stain or Varnish
Stains and varnishes are commonly used to enhance or alter the natural color of wood surfaces while providing protection against moisture and wear. However, painting over stained or varnished surfaces can be problematic. Stains and varnishes create a sealed barrier on the wood, preventing new paint from adhering properly. If you wish to paint over a stained or varnished surface, it’s crucial to thoroughly prepare the surface by sanding it to remove the protective layer and create a rougher texture. Additionally, applying a primer specifically designed for use on stained or varnished surfaces can help improve paint adhesion.
Metallic Paints
Metallic paints have become increasingly popular for adding a touch of elegance and glamour to various surfaces. With their reflective properties, metallic paints can create a stunning visual effect. However, painting over metallic paints can be challenging. The metallic particles in these paints can interfere with the adhesion of other types of paint, resulting in an uneven or bubbled finish. If you decide to paint over a surface previously painted with metallic paint, it’s essential to consult a professional or test a small area first to determine if the new paint is compatible with the metallic finish.
Lacquer or Shellac
Lacquer and shellac finishes are commonly used on wood surfaces to provide a durable and shiny protective layer. Painting over lacquer or shellac surfaces can be difficult due to their smooth and slick nature. The finishes can prevent new paint from bonding properly, leading to issues with adhesion and peeling. To paint over lacquer or shellac, it’s important to follow a meticulous preparation process, which typically involves sanding the surface to create a rough texture and using a high-quality primer to improve paint adhesion.
Water-resistant or Waterproof Paints
Water-resistant or waterproof paints are specially formulated to withstand exposure to moisture and provide protection against water damage. While these paints are ideal for areas prone to moisture, such as bathrooms or kitchens, they are not suitable for being painted over with regular paints. The water-resistant properties of these paints can hinder the adhesion of new paint, leading to issues such as poor coverage and peeling. If you want to change the color or type of paint on a surface previously painted with water-resistant or waterproof paint, it’s best to consult a professional to explore alternative options that work in harmony with these specialized paints.
In conclusion, not all paints are suitable for being painted over with any type of paint. Oil-based paints, epoxy paints, glossy or high sheen paints, chalkboard paints, textured paints, stain or varnish, metallic paints, lacquer or shellac, and water-resistant or waterproof paints are all examples of paints that should not be painted over without careful consideration and proper preparation. Understanding the characteristics and limitations of each type of paint is crucial to achieving a successful and long-lasting paint job.
When in doubt, it’s recommended to consult a professional or conduct a small test patch before committing to painting over a specific type of paint. With the right approach and preparation, you can achieve beautiful and durable results in your painting projects.
